[Form 4] KNOWLES CORPORATION Insider Trading Activity

Rhea-AI Filing Summary

GTES Form 4 (filed 29-Jul-25) details Chief Financial Officer Lawrence B. Mallard’s 27-Jul-25 equity transactions.

• RSU conversion: 39,461 time-based restricted stock units (TBRSUs) were converted into an equal number of ordinary shares (Transaction Code M, price $0.00).
• Withholding for taxes: 17,273 of the newly issued shares were automatically withheld (Code F) at $25.31 to cover par value and tax obligations.
• Net result: Mallard’s direct ownership increased by 22,188 shares to 199,815 ordinary shares.
• Remaining equity incentives: 85,530 unvested TBRSUs continue to vest in roughly equal annual tranches.

No open-market purchases or sales occurred; activity stems from routine vesting of previously granted equity.

Insights

Securities Analyst

TL;DR: Routine RSU vesting—CFO nets +22k shares; no cash sale—neutral corporate signal.

The filing shows an automatic conversion of vested TBRSUs, followed by share withholding for tax liabilities. Mallard’s stake rises to ~200k shares, suggesting continued alignment with shareholders, but there is no discretionary open-market buying. Remaining 85.5k TBRSUs keep future equity incentives intact. From a market-impact perspective this is standard compensation-related activity and should not materially alter the investment thesis for GTES.
